Compact immersion tubes

DIRECT HEATING

Positioning of heating equipment in the bath (gas immersion heater).

DECENTRALISED HEATING

Possibility of fitting in existing baths. Autonomy of different processes. Substitute of all or part of centralised heating systems (support of an overloaded installation).
The ease of installation enables better autonomy in different processes, where efficiency is increased and energy costs are reduced.

EFFICIENT HEATING

No loss of time or energy in order to increase the temperature. The only thermal inertia is linked to the volume of the bath. There is a noticeable improvement in the production of hot water in existing electric water-heating tanks by installing a gas immersion heater on a free manhole. The quality of components provides a degree of simplicity and comfort.

COST-EFFECTIVE HEATING

Thanks to the exceptional output of the compact immersion tube (more than 93% of Net Calorific Value), energy costs can be reduced by 20% to 50%. Furthermore, its direct installation in the bath neutralises losses in energy.

COMPONENTS

The equipment is made up of 3 sub-assemblies:

1 -The burner uses a total pre-mixture of air/gas. The homogeneity of the flame and the high circulation speed of combustion products ensure a relatively high degree of efficiency (from 98% to 93% of NCV), an optimal combustion hygiene and a reduced sound level.

2 - The heat exchanger or coil has a developed length and a tube diameter corresponding to the power to be transmitted. Very compact in design, it has a geometry which can adapt to any shape of tank. It is manufactured in a stainless steel grade adapted to the type of bath to be reheated.

3 - The air/gas pre-mixing line is made up of an air fan and a set of solenoid valves enclosed in a stainless steel sheet housing. The whole unit is controlled by means of a control panel.

POWER

The range of power extends from 30 to 1500 kW.
Until recently, the use of low power compact immersion tubes represented a relatively high cost in terms of investment. THERMIGAS developed a burner almost 9 years ago with a power between 30 and 70 kW at an attractive cost hence solving those problems relating to low-power requirements.
